Desalination Plant

Lummus Consultants has supported the Southeast Asian water sector with independent engineering services for more than two decades, including a desalination plant that produces 137,000 m3 per day of potable water for domestic consumption.

The plant is the country’s fourth large-scale desalination plant and first large-scale, dual-mode water treatment facility designed to treat seawater and reservoir water to produce potable water. The facility entered commercial operation in 2020, designed with a comprehensive pretreatment system, a two-stage reverse-osmosis design to accommodate the differing specifications of the two feed waters, and a post-treatment potabilization plant.

Beyond its large-scale water management function, the plant further advances its sustainability profile by locating the water treatment equipment and facility fully underground and covered by green space that serves community recreation needs.

In 2021 Lummus Consultants provided comprehensive technical advisory services in advance of a party acquiring an equity stake in the desalination plant. The project involved a technical review and condition assessment of plant assets and contract agreements, including an analysis of its design, build quality and condition, performance and reliability, long-term operations and maintenance arrangements, and operational expenditures.

A key part of the review was a verification of the health, safety and environmental arrangements, as well as compliance with local and international standards. We also assessed the main operating and performance risks, along with an analysis of the technical inputs to the project’s financial model, including the remaining useful life and decommissioning costs. The client was successful in obtaining an equity stake in the project with assistance and guidance from Lummus Consultants.
